Further, the overhead transportation network may run dedicated lines (such as the vehicle 1102) for faster routes. Also the network infrastructure may be used for transporting goods between markets and central warehouses.
  • the vehicles 1102-1112 may not be tied to any particular route. The vehicles 1102-1112 may use their suspension mechanism to switch to any track at the junctions for their individual routes, or for diverting the traffic to avoid congested sections of the overhead transportation network.
